| Description | pagpAdminGroupCapability is used by the network administrator
to
control the aggregation of interfaces into agports. The default
value of pagpAdminGroupCapability is equal to the value of
pagpPhysGroupCapability on that same interface.
A pagpAdminGroupCapability may be set to restrict which
interfaces
may be aggregated. Any attempt to set an
pagpAdminGroupCapability value that permits two interfaces to
be aggregated together that are prohibited from being aggregated
by the pagpPhysGroupCapability values will be refused.
A given device may place consistency requirements on
pagpAdminGroupCapability values that span multiple interfaces.
For example, one may be changing interfaces 1-4 from group
capabilities 1, 1, 1, 1 to group capabilities 1, 1, 3, 3. The
capability vector 1, 1, 3, 1 may be illegal. The managed device
will refuse a request to set a value in an interface's
pagpAdminGroupCapability variable if: 1) that new value would
result in an illegal combination of values; and 2) the interface
being set does not have its pagpEthcOperationMode variable set
to
off(1).
The pagpEthcOperationMode variable may be used to avoid illegal
combinations of pagpAdminGroupCapability values. As long as a
given interface's pagpEthcOperationMode is in the off state, any
value may be set in that interface's pagpAdminGroupCapability
variable. In the above example, the third interface could be
disabled, the 3 could be written to the third and fourth
interfaces, and the third interfaces re-enabled.
The operating manuals of the managed device must be consulted to
determine the legality of a given combination of
pagpAdminGroupCapability values. |
